Amount in IV Fluid Questions
Given a volume of IV fluid and a dosage expressed in percent, what is the mass of a particular dosage?

Formula:

$$\boxed{\frac{\mathbf{Concentration\; \%}}{\mathbf{100}}x\mathbf{Volume\; (mL)}=\mathbf{Y(Dosage\; Amount\; in\; g)}}$$

Example: Calculate the amount of dextrose in 1000 mL D5W.

$$\frac{\mathbf{Concentration\; \%}}{\mathbf{100}}x\mathbf{Volume\; (mL)}=\mathbf{Y(Dosage\; Amount\; in\; g)}$$

$$\frac{\mathbf{5\; \%}}{\mathbf{100}}x\mathbf{1000\; mL}=\boxed{\mathbf{50\; g}}$$

Example: Calculate the amount of sodium chloride in 2000 mL NS.
Recall NS is 0.9% NaCl (sodium chloride)

$$\frac{\mathbf{Concentration\; \%}}{\mathbf{100}}x\mathbf{Volume\; (mL)}=\mathbf{Y(Dosage\; Amount\; in\; g)}$$

$$\frac{\mathbf{0.9\; \%}}{\mathbf{100}}x\mathbf{2000\; mL}=\boxed{\mathbf{18\; g}}$$
